Abstract Measurements have been performed in a 300 MWe, front-wall-fired, pulverized-coal, utility boiler. This boiler was retrofitted with boosted over fire air injectors that allowed the operation of furnace under deeper staging conditions. New data are reported for local mean gas species concentration O2, CO, CO2, NOx, temperatures and char burnout measured at several ports including those main combustion staged regions. Comparisons present our previous measurements this boiler, prior to...
Measurements have been performed in a 300-MW e , front-wall-fired, pulverized-coal utility boiler. New data are reported for local mean gas species concentrations of O 2 CO, CO and NO x temperatures, charburnout measured at several ports the boiler including those burner region. They complement previously obtained same before being retrofitted with low-NO burners over-fire air ports. During current experimental work, considerable effort was made to assure minimum variations on operating...
Abstract This paper describes the results of an experimental study undertaken in 300 M We front-wall-fired, pulverized-coal, utility boiler. The data reported include local mean gas species concentrations O2, CO, CO2, NOx,, and temperatures measured at several ports boiler including those burner region, incident wall heat fluxes taken around periphery 39 ports. duxes are for two operating conditions. During work here, a considerable effort was made to assure minimum variations on conditions...
This paper describes an experimental and numerical investigation on the co-combustion of propane with pulverized coal, pine shells, textile wastes. Measurements have been performed in a large-scale laboratory furnace fired by industrial-type swirl burner. Data are reported for in-flame major gas-phase species concentration, including NOx, gas temperature, overall char burnout three flames: propane/coal flame, propane/pine shells propane/textile wastes flame. For comparison purposes, data...
ABSTRACT In this paper a mathematical model to describe Circulating Atmospheric Fluidised Bed Combustor (CAFBC) is presented. For the fast section of bed, momentum and energy balance equations are used predict temperature velocity profiles for gas particles. The performs mass balances chemical species (O2, H2O, CO2, CO SO2) with consideration on last being given retention by limestone A bubbling bed considered simulate bottom CAFBC. applied typical conditions boiler results show expected trends
Abstract Numerical predictions of two‐phase turbulent gas‐particle flows are reported for two test cases: a plane jet and an axisymmetric free jet. The numerical algorithm uses Eulerian approach the fluid phase particulate is described by using Lagrangian stochastic model. k ‐ε turbulence model was used to characterize length time scales fluid. In confined influence restitution coefficient on statistical distribution velocities analysed. Particular attention dedicated ε equation corrections...
